This added to the sense that the universe is intelligible and that intelligibility is characterised by simplicity and beauty in the equations of physics.
It seems reasonable that the degree of mutual intelligibility would determine whether two ways of speaking are classified as separate languages or as dialects of the same language.
Now, Ratzinger argues that the only finally satisfying explanation for this universal objective intelligibility is some great subjective intelligence, some mind which has thought the universe into being.
Ratzinger begins with the observation that finite being as we experience it is marked through and through by intelligibility, by a formal structure that makes it capable of being known by an inquiring mind.
